I would spend upwards of $2000 for a pet. It just depends on what it is. Skunk, serval, Doberman, any of those animals can be multiple thousands and I want all of them!
But I don't treat the pets that I have purchased for cheaper (or got for free) any less. The best dog I ever had was only $85 at the pound. It just depends on what you want and what you fall in love with :)
